/**
 * Marks a {@link ValueExtractor} definition so that it is applied automatically when
 * detecting constraints declared on the container type supported by the extractor, causing
 * the constraints to be applied to the container's elements instead of the container.
 * 
 * If needed, this behavior can be changed per constraint using {@link Unwrapping.Skip},
 * causing the constraints to be applied to the container itself:
 *
 * 
 * @SomeConstraint(payload = Unwrapping.Skip.class)
 * SomeContainerType container;
